Supra-molecular alkylalumoxanes

, 1999
Heterogeneous solid supra-molecular alkylalumoxanes. A supra-molecular architecture of a nano-particle foundation on which an alkylalumoxane is built. Supra-molecular alkylalumoxanes comprise (a) an aluminum-oxide nanoparticle, (b) a linkage unit, and (c)

Nucleophilic Gallyl Anions Enable Ga─Au Bimetallic Ammonia Activation

Angewandte Chemie, EarlyView.
Unlocking gallyl nucleophiles: Counterion control enables formation of an unsupported gallyl─gold complex. Gold coordination induces a polarity switch at gallium, enabling cooperative activation of NH3 and related N─H/O─H substrates under mild conditions.

Coordination‐Driven Direct C─H Metalation of N‐Heterocycles With a Superbasic Co(II) Amide Co(TMP)2

Angewandte Chemie, EarlyView.
By enabling regioselectivities that are inaccessible with conventional bases, this study introduces a Co(II) amide platform for the deprotonative C─H metalation of sensitive N‐heterocycles. Subsequent interception of the resulting Co(II) intermediates with external oxidants affords a family of sterically congested, TMP‐substituted heterocycles via C─N ...

Unlocking a Nitrosuccinate Lyase for Decarboxylative Enzymatic Hydronitration

Angewandte Chemie, EarlyView.
The nitrosuccinate lyase CreD catalyzes C–NO2 bond formation using nitrite in water and shows synthetic practicality with high turnover numbers up to 102,000. A combination of protein engineering and computational methods helped to reveal the mechanistic principles that underpin this unique enzymatic activity.

Sustainable Pd‐Catalyzed Aminations “on Dirty Water”

Angewandte Chemie, EarlyView.
Aminations, done safely yet neat, and therefore, quickly, using low levels of Pd, in “dirty water” that must contain 30% KOH; not NaOH, and not at 5%,10%, 20%, 40%, or 50% KOH. Moreover, no base sensitivity of functional groups! Very cool. Thank you, Nature.
